Chennai: Political parties in Tamil Nadu are unanimous and unequivocal in challenging the Centre’s nod to Karnataka government’s proposal to build a balancing reservoir-cum-drinking water project across the Cauvery at Mekedatu, approximately 100 km off Bengaluru, in Kanakapura taluk.

The DMK president MK Stalin announced a stir to condemn the BJP-led government at the Centre over the issue at Tiruchy on December 4. A resolution toward this extent was adopted at a meeting of DMK and its allies convened to discuss the issue on Thursday, even as the AIADMK government geared up to approach the Supreme Court on Friday against the proposed project.

The deputy chief minister O Panneerselvam condemned the development and affirmed that the state will move the Supreme Court. In this regard, Puducherry Chief Minister V Narayanasamy also has reportedly sought legal opinion to move the apex court.

While the Centre’s nod to the nearly Rs 6,000 crore project, which was envisaged to cater to drinking water needs of Bengaluru besides power generation, has brought cheers to Karnataka farmers, the ryots in Tamil Nadu are a peeved lot.

The Central Water Commission (CWC) has given conditional clearance for Karnataka to prepare a detailed project report (DPR). Meanwhile, a group of farmers from Tamil Nadu have reached Delhi to participate in the Kisan Mukti March in support of their demands.
